As Robert said, they acquired two in September. They were placed on the EWR-IAH-LAX route and EWR-MCO. Of course, we're well into November and I have no idea whether they've added a/c or changed the routing .........
I understand that the 777s are intended to replace some or all of the 747s. As you know, CO has a collection of these from various sources.
The 767-400, a souped-up version of the -300, will come along in a couple of years, resulting in the eventual retirement of the DC-10s.
CV990, the Maserati of the skies!
